PATENT OFFICE c OHIO BRASS COMPANY, OF MANSFIELD, OHIO, A. CORPORATIONOFNEW JERSEY CONDUCTOR SUPPORT Application filed .Tune 27.

Our invention relates to conductor supports and particularly supportsfor a trolley wire, and the process of producing the same.

The object of our invention is toprovide a support or ear which may bebuilt up from several parts into a unitary device, thereby permittingvthe various parts of the ear to be made from material particularlysuited to that part, as, for instance, the lips or portion which gripthe trolley wire may be made of rolled or drawn sheet material; the suporting portion may be made of cast or drop forged material, or it may beof rolled material witha separately formed supporting member securedthereto. t

Our invention resides in the new and novel construction, combination andrelationof the various parts herein described and shown in theaccompanying drawing and in the steps covering the process of producingthe am In the drawing Fig. 1 is a side view of one form of our inventionwith a portion in section.

Fig. 2 is an end view of Fig. 1.

Fig. 3 is a plan view of the lip portion of ourvinvention as formed fromsheet material. j r

Fig.4 shows the methodof uniting the lip portion and supporting webportion, j

,Fig. 5 shows another form of supporting portion formed of two separableparts, a web portion and a boss portion.

Fig. 6 is an end view of Fig. 5. Fig. 7 is a sectional view of Fig. 4taken on the line 7-7. g

In the preferred embodiment of our invention we provide a lip portion 1formed of sheet material, as in Fig. 3, and composed of any material.desired such as hard orsoft rolled or drawn copper, brass, bronze,aluminum or-a ferrous metal, and is provided with.

slots or cut away portions 2. The lip portion lis formed into aU-shapedmember of such size as to receive and fit the trolley conductor,after which the lips may be formed about the conductor by a workmaninstalling the device.

In Figs. 1 and 5 are shown two-forms of supporting members for' the lipportion 1.

1929. Serial No. 374,073.

The form 3 shown in Fig. 1 is ada ted a; be

character and securedto the web portion by means of rivets or screwsthrough the parts.- It will be appreciated that our construction 7passing entirely permits of a wide variation in the various materialsfromwhich the device is constructed, as',for instance, the portion 1 maybe made of hard drawn copper and the portion 3 in Fig. 1 maybe made ofcast brass or bronze of. any composition desired, or may be of a cast orforged ferrous material. In Fig. 5 the web 4 may be formed of sheetsteel or any suitable non-ferrous material, while the boss portion 5maybe of a castferrous or non-ferrous material, or forged.

' Referring to Fig.5, the web 4 is formed as shown with the plurality ofprojecting lugs .6 adapted to bepositioned within the recesses 2 of thelip portion, and the web 4 of or MmsrrnLn, onro, ASSIGNORS To rim Fig. 1is providedlwith. the same projecting lugs 6 to be received intheopenings 2 of the lip portion, and these parts having been assembled,the parts are placed in an inverted positionas shown in Fig. 4 and theprojecting portions of the lugs 6 are then fused to form .anintegral'alloyunion with the adjacent I portions of the lip-portion 1 bymeans of an electrode '8.

adjacent parts land 4or 4, and if additional metal is required, itwillzbe applied in the form ofseparate metal rods.

The parts may also be united by means of the oxyacetylene flame, alsowell known to those skilled in the art, but we find that the electricarc process is more desirable." 7

By making the openings 2 a little wider than the projecting lugs 6,thefused metal will flow downwardly throughthe space between the lugs 6 andthe sides of the openings 2, and by placing a carbon mold on the outsideof the parts at the point of weld and hav-.

ing a slight recess therein, this fused metal can be caused to form afillet 9 which tends to brace the web and lip portion against a sidestrain. 7 I i the iorm shown in Fig. 5, the lower faces 10 of the member5 maybe undercut so as to rest upon the up'perpor'tion of the lipportion 1 and thereby tend to brace the lip portion and web 4" againstrelative side move ment. .7 v

It will be apparent tha-t'we have provided a built'up supportior atrolley wire of a plurality of parts united to each other and the Imethod of forming such device and in which the use of a large range ofmaterials is provided. Having described our im; r
